I tried replacing the washers spring the cartridge and faucet extenders on my tub faucets the hot water is still leaking out maybe even worse now can I eliminate the extender and go to a shorter cover that would fit exactly over the cartridge with the handle to turn on and off . what I'm getting at is I seen covers that were at like 2 inches long can I go to that size and eliminate the plastic extender which is 3 inches or more long and seems awful wobbly with the plastic exteI'm hoping this may eliminate the leak
